Why does charging stop at 80%?

Your iPhone may pause charging at 80% to prevent overheating as part of iOS 17's temperature management. Charging will resume once it cools down, and moving it to a cooler spot can help speed up the process.

Why does the power bank get warm during use?

It's normal that the power bank may feel warm during use as magnetic charging converts electrical energy into electromagnetic waves, generating heat.

How can I prevent overheating?

To reduce overheating, avoid using your iPhone or running power-intensive apps while it’s charging.

Why is my magsafe power bank providing fewer charges than expected?

Due to a 30% to 40% capacity loss from battery cell and circuit inefficiencies during charging, a fully charged ESR 10,000mAh magsafe portable charger effectively provides about 6,000mAh to 7,000mAh ofusable power to your devices.

What should I do if my phone isn’t charging with the MagSafe power bank?

Ensure your iPhone is MagSafe-compatible (iPhone 12 series or later), your case is under 2 mm thick, and there are no metal accessories, credit cards, or pop sockets between your phone and the power bank.
